My computer booted last night while the 3 case fans were unplugged but when i powered it down and plugged them in it would spin the fans for a moment and then it would stop...almost like it was getting partial voltage. My psu is a 500watt corsair so it is of good quality and decent power and i have a fx6300, gtx650 ti boost, asrock 880le, 2nzxt fans and one king air i think its called, nzxt source 210 elite case, wd 1tb hdd, and a generic 20 dollar cd/dvd burner...today when i went to go try to get it to boot with everything connected, only the psu and hdd would spin up. So any help or explination to why this is happening would be appreciated. Also all parts are new thanks
